Games like gamma world

Gamma World is a science fantasy role-playing game, originally designed by James M. Ward and Gary Jaquet, and first published by TSR in 1978. It borrowed heavily from Ward's earlier product, Metamorphosis Alpha.

Gamma World takes place in the mid-25th century, more than a century after a second nuclear war had destroyed human civilization. The war that destroyed civilization in Gamma World is only vaguely described in most editions of the game, and what details are provided change from version to version:

All editions, however, agree that the cataclysm destroyed all government and society beyond a village scale, plunging the world into a Dark Age. In many editions of the game, technology is at best quasi-medieval (in the first edition, the crossbow is described as "the ultimate weapon" for most Gamma World societies). Some, such as the 2003 and, to a lesser degree the 2010 edition, feature advanced technology that is well known and often easily available. In contrast, super-science artifacts in earlier editions were risky to use due to the average Gamma World character not knowing how to properly operate such devices, or possibly even what the device is at all. The post-apocalyptic inhabitants of Earth now refer to their planet as "Gamma World" (or "Gamma Terra" in later editions).
